Book Description
The identification of Atlantic herring stocks inhabiting both sides of the northern Atlantic has been the subject of numerous investigations for many years. In more recent years, the discreteness of the spring and autumn herring populations in the Gulf of St. Lawrence was established, a separation important for delineating proper fishery management units. Otolith characteristics, such as shape and first year's growth, were used in both the Gulf and Newfoundland regions, but the method used requires well-trained technicians and was criticized because of its subjectivity. A semi-automated microcomputer-based measuring system was developed for otolith measurements in the Gulf region to eliminate such subjectivity. The method uses a microscope with a drawing tube and a digitizer interfaced to a personal computer which analyzes the digitized otolith measurements using software packages. This report presents results using this system to separate herring spawning groups by otolith morphometrics.

An Economic Assessment of the Herring Purse-seine Fleet Restructuring Plan of 1983 : the Ten-year Management Plan at Mid-term

Book Description
The herring purse seine fleet is relatively new in Atlantic Canada, having its first commercial spurt as a distinct fishery during World War II. However, it has been subject to recurring boom and crisis brought about the variations in markets, herring stocks and quality. In 1983, the price paid for herring and the allowable catch were such that purse seiners were sustaining losses and the outlook was poor. A 10-year program was undertaken in which each purse seine licence holder was given a quasi-property right in a share of the allowable catch, which could be sold with the seller keeping the monetary reward. The buyer could accumulate extra quota which promised a greater measure of profitability. The fishery of 1988 marked the 5th season of the program. This study was undertaken to appraise the response of the fishery in an atmosphere of limited entry with transferable quotas, to what extent the objectives of the program were being achieved, and to clarify the determinants of the developments in the fleet.
